3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project area (Drawing 5) contains an existing drive, a retaining wall, a buried natural gas line, a sanitary sewer line
and associated easement and wooded land. The site is located within the Forsyth Technical Community College
campus. Buildings and parking areas are located in the vicinity of the site.
3b. List the total estimated acreage of all existing wetlands on the property:
Wetland=0 Ac
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Streams=250 LF
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to stabilize the stream and associated slopes on the western side of the stream.
3e. Describe the overall project in detail, including the type of equipment to be used:
The western stream bank has failed and the slope is eroding, slumping and undermining a gas pipeline and a retaining
wall. If not stabilized, the stream will also undermine an asphalt drive and parking ares located up -gradient of the wall.
Because there is a gas line, a steep slope, a retaining wall and unstable soils, it is necessary to access the area for
repairs from the eastern side of the stream. It is necessary to temporarily divert the stream from the construction area
through a culvert that will also serve as a construction crossing. In order to stabilize the slope, a retatining wall will be
constructed on the western side of the stream. Upon completion of the stream and slope stabilization measures, water
will be diverted back into the existing channel and the culvert will be removed. Graders, haulers, excavators and other
heavy equipment will be used during construction activities.
4. Jurisdictional Determinations

temporarily by-passed. Measures will be taken to minimize the stream impacts as construction equipment works on the
opposite side of the stream. Following construction of the wall, the stream banks will be restored to pre -construction
conditions and will be seeded, matted and live staked before water is diverted back into the channel. Areas of temporary

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project area includes a failed stream bank and a severely eroded slope that is actively contributing sediment to the stream
during precipitation events. Aside from stabilizing the bank, preventing a gas pipeline, an existing retaining wall and an
adjoining asphalt -paved driving/parking area from undermining, the project will prevent further sediment from eroding into the
stream.
The project has been designed so that work within the existing stream will be completed in the dry. The stream segment that
must be temporarily impacted and by-passed will be restored, matted, seeded and live staked upon completion of the
stabilization measures. Additionally, log drops have been designed within the stream segment to limit future head -cutting and
add to the overall stability of the stream.
In order to prevent scour and protect the stream channel down -gradient of the culvert, it is necessary to use rip rap. The rip
rap is to be keyed into the existing bed and banks, in an effort to leave the stream flow unobstructed.
A staging area will be located east of the construction area. A skimmer basin has been designed to treat precipitation runoff
from the staging area to prevent sediment from washing into the stream.
Upon completion of the proposed project, the coffer dam will be removed and water will be diverted back into the stream. The
overall project should improve the stability and stream quality.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The clearing limits will be staked and silt fence will be used. A temporary coffer dam will be installed that will function to divert
water into the by-pass culvert. During construction, water will be routed through the culvert. Appropriate stream bank
protection will be provided in the channel during construction and all excess excavated material will be immediately removed
from the stream bank crossing area. The rip rap is being keyed in to further minimize the impacts to the stream. Following
construction, disturbed banks will be restored to similar pre -construction conditions, matted and seeded/live staked. Upon
completion of the project, the temporary sand bag coffer dam will be removed and flow will be diverted back into the stream.

Wetland Rules (15A NCAC 2H .1300), DWQ Surface Water or Wetland Standards,
❑ Yes
® No
or Riparian Buffer Rules (15A NCAC 2B .0200)?
2b.
Is this an after -the -fact permit application?
❑ Yes
® No
2c.
If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s):
3.
Cumulative Impacts (DWQ Requirement)
3a.
Will this project (based on past and reasonably anticipated future impacts) result in
❑ Yes
® No
additional development, which could impact nearby downstream water quality?
3b.
If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy. If you answered "no," provide a short narrative description.
Additional development will not result as a result of this project that could impact nearby downstream water quality.
4.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
❑ Yes ® No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act
❑ Yes ® No
impacts?
❑ Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
We consulted the USFWS Website to determine if federally protected endangered or threatened species inhabit Forsyth
County, NC. The bald eagle, bog turtle, small-anthered bittercress and northern long-eared bat are listed as federally
protected species. The waterbodies on the site and nearby properties are small and do not provide habitat for the bald
eagle. Federally protected bog turtles do not occur on the site and there are no plans to transport turtles that are similar
in appearance to or from the site. Suitable habitat for small-anthered bittercress is not present on the site.
Wooded areas could afford suitable summer roosting habitat for northern long-eared bats. Similar habitat was observed
on nearby properties. Based on a review of the June _1_2016_NLEB _HUC12 NLEB shapefiles obtained from the Raleigh
Ecological Services Field Office website, the 12 digit HUC with the nearest confirmed hibernation and/or maternity sites is
located approximately 95 miles from the site. Therefore, tree clearing outside of the pup season (June 1 to July 31) is not
likely to adversely affect the NLEB. If tree clearing activities cannot be conducted outside of the pup season, then the
applicant will rely on the final 4(d) rule and any take will be considered exempt from the ESA.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
Based on a review of the NOAA Essential Fish Mapper, the site is not located in or near an area designated as essential
fish habitat. Best management practices and the construction of a skimmer basin will prevent sediment from entering down -
gradient waterbodies which may contain essential fish habitat.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation
❑ Yes ® No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
We reviewed the SHPO Map (http://gis.ncdcr.gov/hpoweb/) to identify historic and/or archaeological resources on the site
or on nearby properties. The map does not identify eligible for listing properties at the site or on nearby properties. A copy
of the map is included as an attachment.
8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA-designated 100-year floodplain?
❑ Yes ® No
8b. If yes, explain how project meets FEMA requirements:
8c. What source(s) did you use to make the floodplain determination? 3710682400J (Drawing 4)

NEW YORK DOT DISSIPATOR METHOD
FOR USE IN DEFINED CHANNELS
(Source: "Bank and channel lining procedures", New York Department of
Transportation, Division of Design and Construction, 1971.)
NOTE: To use the following chart you must know:
(1) Q full capacity
(2) Q:n
(3) V full
(4) VIa
where Q = discharge in cfs and V = Velocity in FPS.
ESTIMATION OF STONE SIZE AND DIMENSIONS FOR
CULVERT APRONS
Step 1) Compute flow velocity V at culvert or paved channel outlet.
Step 2) For pipe culverts D. is diameter.
For pipe arch, arch and box culverts, and paved channel outlets,
D0 = Ao where A. = cross -sectional area of flow at outlet.
For multiple culverts, use Da = 1.25 x D. of single culvert.
Step 3) For apron grades of 10% or steeper, use recommendations
For next higher zone. (Zones 1 through 6).

DETERMINATION OF STONE SIZES FOR DUMPED STONE.
CHANNEL LININGS AND REVETMENTS
Step 1. Use figure 8.06.b.3 to determine maximum stone size (e.g. for 12
Fps = 20" or 550 lbs.
Step 2. Use figure 8.06.b.4 to determine acceptable size range for stone
(for 12 FPS it is 125-500 Ibs. for 75% of stone, and the maximum
and minimum range in weight should be 25-500 lbs.).
NOTE: In determining channel velocities for stone linings and revetment,
use the following coefficients of roughness:
Diameter Manning's Min. thickness
(inches) "n" of lining (inches)
Fine 3 0.031 9 12
Light 6 0.035 12 18
Medium 13 0.040 18 24

REPAIR THE DIVERSION RIDGE. CAREFULLY CHECK OUTLETS AND MAKE
TIMELY REPAIRS AS NEEDED. WHEN THE AREA PROTECTED IS
PERMANENTLY STABILIZED, REMOVE THE RIDGE AND THE CHANNEL TO
BLEND WITH THE NATURAL GROUND LEVEL AND APPROPRIATELY STABILIZE

2. Divert all surface water from the construction site onto undisturbed areas
adjoining the stream.
3. Keep stream crossings at right angles to the stream flow.
4. Align road approaches with the center line of the crossing for a minimum
distance of 30 feet. Raise bridge abutments and culvert fills a minimum of I
foot above the adjoining approach sections to prevent erosion from surface
runoff and to allow flood flows to pass around the structure.
5. Stabilize all disturbed areas subject to flowing water, including planned
overflow areas, with riprap or other suitable means if design velocity exceeds
the allowable for the in -place soil (Table 8.05a, Appendix 8.05).
=ENCE 6. Ensure that bypass channels necessary to dewater the crossing site are
stable before diverting the stream. Upon completion of the crossing, fill,
compact, and stabilize the bypass channel appropriately.
7. Remove temporary stream crossings immediately when they are no longer
needed. Restore the stream channel to its original cross-section, and smooth
and appropriately stabilize all disturbed areas.
8. Any in -stream sediment control measures must be removed upon
stabilization ofthe area.
